JOHN ANDREW DRIVER, OF ALLEGHENY, PENNSYLVANIA.

METALLIC CAR.

SPECIFICATION forming part of Letters Patent No. 742,846, dated November 3, 1903. Application filed July 1,1903. Serial No. 163,967. (No model.)

To all whom it may con/ceri.

Be it known that I, JOHN ANDREW DRIVER, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Cars, of which the following is a specification.

This invention relates to improvements in metallic cars, and has special reference to a car especially adapted for coal Aand provided with means for operating spring-closed doors in the bottom thereof.

The main object of my invention is the provision of a novel form of doors and operating mechanism substantially as disclosed herein.

Figure 1 is a longitudinal sectional view of the car made according to and embodying my invention. Fig. 2 is a central cross-section thereof. Fig. 3 is a similar view of Fig. 1 with the doors open. Fig. et is an enlarged detail view of one of the doors detached. Fig. 5 is a bottom plan view of the car, showing the position the doors and operating mechanism assume.

Referring to the drawings, the numeral 1 designates the car, which is mounted upon the suitable frame 2, carried by the trucks 3. This car is provided with the inclined end walls 4 and the two centrally-arranged oppositely-inclined walls 5, which provide a pocket or space 6 for the reception of the door-operating mechanism. The doors 7 are arranged in tandem and are secured, by means of the hinges S, to the lower edge of the inclined walls 5 and are adapted to be held normally closed by means of the spring 9, which is connected to the plate 10.

The rod 11 is adapted to be normally held in engagement with the catches or latchhooks 12 by means of the springs. This latch-rod 11 is connected to the doors, so that the springs will operate thereon to hold the doors closed and in engagement with the latch-hooks 12'. To operate the doors and open the same, I provide a shaft 13, which is journaled in the bearings 14 in the support 14., and carried upon this shaft is a pulley 15, over which passes the operating-chain 17, which has one end connected at 16 and the other end connected at 18 to the shaft 18, This shaft 18 is journaled in the bearings 19 and in the bracket 19 and has a gear 19b meshing with the gear 19, carried by the shaft 19, provided with the operating-wheel 20, in order that the shafts 13 and 18 may be revolved to cause the chain to open the doors, a dog 2l and ratchet 22 being employed to check the movement of the shaft 19d and hold the same when desired.

From the foregoing description, taken in connection with the drawings, it will be noted that by turning the operating -wheel the chain connected to the shaft thereof will raise the latch and allow the weight of the mateL rial within the car to force the doors open, but 4that as soon as the doors are closed the spring will operate the latch and bar so as to cause it to engage with the catches and hold the doors closed. It will also be noted that I provide a space for the operating mechanism, so that the mechanism will be at all times out of contact with the contents of the car and will be in a position to be readily accessible in case of breakage and when in need of re'- pair. It will also be noticed that I provide self-closing doors for cars of this character which can be operated by one Vman instead of a number, as is the present practice.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a metallic car having a centrally-arranged opening in the bottom thereof, of doors for controlling the said opening, and mechanism for operating said doors comprising a springactuated latch-bar carried by each door, a chain connected to each latch-bar, and an operating-shaft connected to the other end of the chain for operating the latch-bar and opening the doors.

2. The combination with a metallic car having a centrally-arranged opening in the bottom thereof, of doors for controlling the said opening, and mechanism for' operating said doors comprising a spring-actuated latch-bar carried by each door, a chain connected to each latch-bar, and operating means connected to the other end of the chain for operating the latch-bar and opening the doors.

3. The combination with a metallic car, having a car-body provided with inwardly-inclined ends terminating near the center of the car, oppositely-inclined walls arranged centrally of the body of the car and having their lower edges above and in line with the lower edges of the end walls so as to provide an opening between each end Wall, and doors arranged in tandem hingedly connected to the lower edge of the centrally-inclined walls for normally closing the openings thereof, of mechanism for operating said doors journaled in the. space below the centrallyinclined walls, comprising a spring-actuated latch-bar carried by each pair of doors, a chain connected to each latch-bar, and means connected to the chain for operating the latch-bar and opening the doors.

4. In a metallic car, the combination with a car-body having inwardly-inclined ends ter. minating near the center of the car, oppositely-inclined walls arranged centrally to the body of the car andhaving their lower edges above and in line with the lower edges of the end walls 'so as to provide an opening between each end Wall and doors arranged in tandem and hingedly connected to the lower edge of the centrally-inclined walls for normally closing the openings, of mechanism for operating said doors journaled in the space below the centrally-inclined wall, comprising a springactuated latch-bar carried by each door, a chain connected to each latch-bar, and an operating-shaft connected to the other end of the chain for operating the latch-bar and opening the doors.

5. In a metallic car, the combination with a car-body having inwardly-inclined ends terminating near the center of the car, oppositely-inclin'ed walls arranged centrally to the body of the car and having theirlower edges above and in line with the lower edges of the end walls so as to provide an opening between each end wall and doors arranged in tandem hingedly connected to the lower edge of the centrally-inclined walls for normally closing the openings, of mechanism for operating said doors journaled in the space below the centrally-inclined wall, and comprising a spring-actuated latch-bar carried by each set of bars, a chain connected to the latch-bar, an operating-crank connected to the opposite end of thevchain for operating the latch-bar and opening the door, and a guide-pulley over which said chain passes.

In testimony whereof I affix my signature in presence of two witnesses.

JoHN ANDREW DRIVER.
